“The idea behind PSTN Connect is to provide users with a flexibility they don’t have today. For example, the vIPer Universal Secure Phone will appeal to those whose installations currently use the PSTN network, but who plan to migrate to voice over IP; users who currently have voice over IP networks; and others who plan to stay with traditional PSTN,” said John Cole, vice president of Information Assurance for General Dynamics C4 Systems. “It’s about protecting our customers’ investments by providing a product that will accommodate evolving communications technologies.”

Introduced in 2006, the Sectéra vIPer Phone remains the only voice over IP phone certified by the NSA to protect information classified Top Secret and below over commercial networks. The vIPer Universal Secure Phone, with PSTN Connect, will be submitted for NSA certification testing in the third-quarter of 2008. The vIPer, with PSTN Connect, upon successfully completing certification testing, will provide secure phone users with a cost effective solution for replacing legacy secure phones, including the Secure Telephone Unit (STU-III).
